Write to SLOG every 5 minutes?

Hi all,

I run TrueNAS CORE 13.0-U6.1 on my main system and I used to have an HDD based NFS datastore for ESXi. No big deal, just home lab messing around with products I also encounter in my workday. And even if I did not need it there was this empty M.2 socket on the mainboard screaming "fill me" and I got an Intel Optane factory new pretty cheap, so I added an SLOG to the pool just because I could. Being fully aware that it does not help my more common SMB workloads the slightest.

Now I retired my ESXi server and repurposed the hardware to run TN SCALE on bare metal. For obvious reasons I assume.

So there is (to my knowledge) no share and no service that does synchronous writes to my pool.

Can anybody explain this pattern?
